Kilby Jeep Air Compressor - Don't Leave Home Without It!

An onboard air system is a valuable resource for any 4x4. The AirBoss system repositions the alternator to fit a beltdriven York compressor underhood. The AirBoss system includes all of the necessary items to equip '91-'08 Jeep Wranglers with a usable onboard air source. The system is shown installed on an '07 Jeep Wrangler JK.

We all know the importance of lowering the air pressure in the tires before tackling a trail, but many neglect or forget to bring a portable air source to air up the tires again before hitting the pavement at day's end. Those caught without an air source of their own typically wait their turn to use their buddy's 12-volt air compressor after he's done with it, delaying the trip home for more than just themselves. One way to ensure you don't end up being "that guy" is to install an onboard air compressor such as the AirBoss system from Kilby Enterprises.

The AirBoss system is a beltdriven onboard air system that can be used to air up tires, operate air tools, or even to actuate ARB Air Lockers. The heart of the AirBoss system is a York compressor that mounts underhood next to the alternator, so that the compressor-clutch pulley is in line with the engine's serpentine fan belt. At the flip of a dash-mounted switch, the compressor clutch will kick on, and the belt will drive the compressor to fill an underbody-mounted air tank. And since the AirBoss system permanently mounts to your vehicle, your 4x4 will never again be without an air source.

In addition to the York compressor and clutch, the AirBoss system includes a compressor-mounting kit, a CNC-milled air manifold, an intake filter, a coalescing filter, Rotolock air-line fittings, 35 feet of 3/8-inch Goodyear Insta-Grip hose, a 2-1/2-gallon air tank, and installation hardware. AirBoss kits are available for '91-'08 Jeep Wranglers to fit most available engines in that year span and '78-'86 Jeep CJs with 304-360 V8 and V-belt 258 I-6 engines. Kits are also offered for various Dodge and Chevy engine applications. Check out the captions for installation highlights.
